Format SQL

Beautify and Minify SQL for Any Dialect

Paste a cramped, one-line query and get back clean, consistently indented SQL you can actually read — or collapse a formatted query back down to a single line. It handles 20 dialects, including PostgreSQL, MySQL, SQL Server (T-SQL), Oracle PL/SQL, BigQuery, Snowflake, Redshift, SQLite, and more, so keywords and syntax are laid out the way your database actually reads them. You control the indent size and whether keywords come out UPPERCASE, lowercase, or exactly as typed.

Most online SQL formatters send your query to a server to do the work. This one doesn't. Every keystroke is formatted in your browser, so table names, column definitions, and hard-coded values never leave your device — which matters when the query on your clipboard came straight from a production log.

An honest note: this tool formats SQL, it doesn't run it. It won't execute your query or check that it's valid against a real schema, so it can reformat SQL that would still error against your database. Minify also removes comments while it collapses whitespace.

• Code review: expand a teammate's dense one-liner so the joins, filters, and grouping read at a glance.
• Migrations: standardize indentation and keyword case across a schema file before you commit it.
• Debugging: paste an ORM-generated query pulled from your logs and see the exact statement that ran.
• Embedding: minify a finished query into a single line for a config file, a string literal, or an API payload.
• Learning: reformat an unfamiliar query so the clause order — SELECT, FROM, WHERE, GROUP BY — becomes obvious.
• Dialect matching: switch the dialect to BigQuery or T-SQL so vendor-specific syntax indents correctly instead of breaking the layout.

Privacy: This tool runs entirely in your browser. Your SQL is never uploaded, logged, or sent anywhere — there is no server, no account, and nothing to sign up for.
